Preparing the board

Identify parts

Look at the parts you got and make sure you can identify them

Note: we now use different switches and jacks than in the second photo

For resistors, pay attention to the color bands as follows:

  • 100: brown black brown gold
  • 330: orange orange brown gold
  • 1k: brown black red gold
  • 4k7: yellow purple red gold
  • 10k: brown black orange gold
  • 47k: yellow purple orange gold
  • 100k: brown black yellow gold
  • 220k: red red yellow gold
  • 470k: yellow purple yellow gold
  • 1M: brown black green gold

Now look closely at the board diagram. Make sure you know what symbols represent resistors, capacitors, IC sockets, transistors, FETs, diodes, wires, etc..

Drill the holes
  • Use a dremel and a tiny bit (#60 or #66) to drill a hole on every circle on the soldering side. sells the bits, part number 5876-409-66
  • Make sure to drill 8 or 14 holes for each IC
  • Periodically check the opposite side to make sure you’re still lined up (hold the drill vertical, not at a slant)
  • Depending on the IC sockets you have, you may need to ream out the holes for the IC sockets using a thumbtack or a larger drill bit. If your board is too thick (e.g. masonite), you may need to counter-sink the IC socket holes
